PBOPELLING MECHANISM FOR AIR NAVIGATOBS.

. Application filed December 11, 1925. Serial No. 74,683.

This invention relates to improvements in the art of aerial navigation, particularly to means. which may equally well be used to propel and manoeuvre lighter than air and o'heavier than air crafts, such as dirigibles,

balloons, aeroplanes, or the like.

The improvements can also be applied to inaic'line crafts and vehicles to-be operated on An object of the invention is the provision of novelly situated propellers, and associated controlling mechanism. v

For further comprehension of the invention, and of the objects and advantages there 15 of, reference will be had to the following description and accompanyingdrawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

' Fig. 13 shows another modification illustrating the employment of the device on an observation balloon.

. Fig. 14 shows a modification illustrating the device employed together with a novelly constructed body. p

' The body 10 of anairship of suitable material and shape is provided with propellers Fig. 12 shows a modification of "the inven-- 11, hereinafter further described, so situated that the planes of rotation of the propellers are different. Referring to Fig. 1, it is readily seen that the propellers located at the front and back are situated on a tangent to these curved parts, while the center propellers align withthe body 10, thus providing differentplanes of rotation. Likewise in Figs. 12 and 13 the propellers are positioned tangential to curved portions of the balloon thereby providing. different planes of rotation. .This novelfway of situating the propellers associated with-controlling mechanism is an important improvement over the old methods of allowing propellers to be in the same plane.

The ship, as is usual, has alower cabin 12,

with windows 13, and at one end the controlling chamber 14 in which the controlling mechanism .15, more completely illustrated in Fig. 8, is situated, having controlling wires 16to the different propellers.

A bottomv compartment 17 for the carrying of freight or ballast has support wheels 18 to permit running along the ground and bumpers 19 with springs 20. For holstin g the member 17 to the. cabin 12, ropes 21 engage over drums 22, operated by hand wheels 23, while for detachably securing tlfe member 17 to cabin 12, tongues 24 depending from 17 'pass through eyes 25 in the cabin 12, and wedges'26 engage'said tongues. Stair- 'ways 27may be provided in said bottom compartment. The propellers. 28 are mount: ed on said cabin in different planes, and are also controlled from 15. These ropellers aid in the better operation of the ship. The

propellers are driven from shafts 29 connected to the engines of the ship.

The propellers are similar to the one described in-a co-pending application, Serial No. 33.645. filed May 29, 1925, but have a novel controlling means. The drum 30 is rotatable on shaft 31 having an eccentrical cylindrical portion 32 provided on its external surface withball bearings 33 rotatably engaging collar 34 having fixed thereto a propeller wing 35 slidably projecting from a slot in the said drum 30. R-igidly fastened to said drum is a gear wheel 36 having a journal 37 and is hollow to provide a journal of. shaft 31.-- Thedriver gear 38 engages said gear 36, and is connected by shaft 39 to the engines of the ship. The part 40 is only a supporting bracket, and is stationary while I the adjacent drum is revolved from said gears,.and as the drum revolves the propeller wing 35 is pushed around part 32, performing an inward and outward motion. Simultaneous with the inward and outward motion of the wing is another motion, namely, the forward rotating motion of the wing about member 32. It .is readily seen that these motions cause a propelling action. The timing of this inward and outward motion may be changed by turning shaft 31 which is accomplished by the controlling .meehanism 15, and in this manner the ship is directionally controlled.

The controlling mechanism 15 consists of a panel '41 having at its ends standards 42, engaging a shaft 43 having a plurality of cone elements 44 thereon, engageableinto wheels 45 having control levers 46 each of which is equipped with a pivoted lever 46 to lock the control lever 46 at various angles to a fixed gear segment 46, and each of said wheels have attached controlling wires 16 leading to the various propellers throughout the ship and engaged over shafts 31 therein, and fastened'theret'o as at 51, whereby turning said wheels thetiming of said propellers is changed as before explained. The said wheels may be individually controlled by handles 46, or simultaneously controlled by pressing in lever 47 which is thus held by catch and spring 48; the said cones 44 then engaging the wheels and the pivoted levers 46 are locked to control levers 46 by means of locking rings 46 which may be swiveled at the-top of the said control lever, then turning main wheel 49Ico-acts to all wheels. Upon releasing the catch and spring 48 the spring 50 returns the shaft '43 to normal disengaged position.

The rear end of the body in Fig. 14 shows a corrugated surface with abrupt edges to allow additional lateral surface.

The operation of thedevioe will be readily understood without furtherexplanation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
